Criteria for using campgrounds?

Based on what you've told us, you are not eligible to utilize MWR facilities. Use of MWR facilities (includes campgrounds) is primarily for active duty, retired military, and 100% DAV. Although, there are a few other categories that are eligible. However, military campgrounds are not a benefit provided to the typical veteran.
